[Gluster-devel] New dev release - GlusterD2 v4.0dev-4

[Prashanth Pai]

Hi all,

We have a new development release of glusterd2.

## New changes[1]
* Add experimental support to run multiple glusterd2 instances per node
    - bricks are no longer strongly coupled to nodes and are associated with glusterd2 instances
    - will help when we add functional tests to CI and also during development
* Introduce volume status API as reference implementation of transaction result aggregation
* Start brick processes for real during volume start operation
* Generate client and brick volfiles using templates
    - quick workaround to get things moving until real volgen arrives

Other minor changes:
* Completely remove external etcd binary dependency
* Fix all golint issues and enforce checks henceforth for further contributions
* Bump up minimum go version required to 1.6 (fully supports vendoring)

Things we will be working on:
* Continue working on dynamic volgen functionality
    - will replace current temporary template based volfile generation
* Implement Sun RPC in Go as an easy consumable library.
    - will allow other C components to communicate with glusterd2 without
      having to change their existing code
    - also driven by lack of availability of high-level C API for grpc
* Initiate broader discussion around component pluggability[2]
